Full description
After pickup from your hotel around 3:00 PM, depart from Chong Lard Pier in Ko Yo Yai for a 15-minute trip to Koh Yao Noi. Board your longtail boat then head first to Koh Nok, a roughly 10-minute journey. Visit a beautiful beach with stunning vertical cliffs and trees surrounding it. Take photos, relax on the beach, or go up to the viewpoint for a scenic lookout. Next, move onto the emerald lagoons of Hong Island, whose bay is surrounded by mountains. Chill out on the soft sandy beach, or swim and snorkel in the crystal clear water with a variety of colorful marine life of all shapes and sizes. Fresh seasonal fruits will also be served on the beach. From Hong Island, get away from the crowds with a visit to the peaceful Lading Island for some more beach, swimming, or snorkeling time. At 5 PM, make your way to Pakbia Island to watch the stunning sunset over the ocean horizon from the comfort of the beach. At 7 PM, go to Ko Pak Ka or an island in the area to see the glowing luminescent plankton. Please note that bioluminescent plankton visibility is dependent on the weather and how close the Moon is to Earth on that day. Start making your way back to Koh Yao Noi and Koh Yao Yai 30 minutes later, before being transferred back to your hotel.
